This may not be PC, but an AIDS vaccine of the type they describe is a bad idea. That type of vaccine does nothing to eliminate the presence of the virus. As such, it gives the virus ample opportunity to mutate. We are talking about a virus with known rapid mutation, which would be present in the blood stream of an infected person until he or she dies.
This "vaccine" would promote participation in the same types of behavior which caused AIDS to spread in the first place. These behaviors are proven to be detrumental to the health of the participant and their partners. By this I don't mean homosexuality per se, but specific activites and behavioral patterns that can be present in straight or gay people.
I agree. Also, while the AIDS patients are being prolonged through the use of the "AIDS cocktail" they also appear to be developing resistant strains of TB and other infections, which can be passed on to those who do not participate in risky behaviour.
